Ever since I was old enough to dream,I have imagined myself flying with the eagles.My love of flying has shaped the way I live and the person I have become.Two years ago that passion rocketed to new heights when I visited Embry Riddle Aeronautical University in Arizona.For a whole week I lived in a college dorm,roomed with a total stranger,and best of all,I flew!

My group took part in activities from learning about the history of aviation（航空）to flying in pilot training simulators（模擬器）.At least once a day,I was lost in one of the world's best training aircraft,the Cessna 182.I received thorough ground instruction,and also got to fly.In total,I flew five hours toward receiving my private pilot's license.In that joyous week,my passion for aviation grew even stronger.Now,whenever I see a plane flying overhead, I feel a sense of pride,thinking I've done that.

During my time above the Arizona desert,I learned not only about the mechanics and techniques of aviation,tout also about myself and how I see the world.Floating in that seemingly endless sea of air,I became aware of the variety and the complexity of the humanity below.On the ribbons of roadways,each tiny car carried people with hopes and ambitions.I wondered if any of them had ever wished to fly like an eagle.I realized they must have their own strong desire.That's what makes us unique.We always try to respond to something special inside us.I also realized that I was especially fortunate to be making my own dream come true.

Everywhere I go,I hear,"Do what makes you happy,and you will be happy."It sounds like standard advice,but I've really thought about it and taken it to heart.I couldn't care less about what benefits I receive.I know I am already in hot pursuit of my dreams.Even if they change,and even if they finally don't involve aviation,I'll always aim to fly with the eagles.

1.What made the author successful?

A. His practice. B. His love for flying.

C. His imagination. D. His roommate.

Stephen Hawking was born in Oxford, England on 8th January, 1942. He went to school in St. Albans—a small city near London. Although he did well，he was never top of his class. After leaving school, Hawking went first to Oxford University where he studied physics，and then he went to Cambridge University where he studied cosmology （宇宙學）. As he himself admitted he wasn't very serious about studying. He was a very lazy student, and did very little work. However, he still achieved extremely good marks.

Hawking first noticed something was wrong with him at the age of 20. He started to bump into things, and often fell over for no reason. When he visited his family at Christmas time, his father was so worried that he was sent to hospital for a test. Finally, the result came back. Hawking had motor neurone disease（運動神經(jīng)元�。�，an incurable illness which causes the muscles of the body to waste away. Doctors said he would die before he was 23.

At first, Hawking became extremely depressed（憂郁的）. After a while, though, he began to see his life in a different way. As he later wrote, “Before my illness had been diagnosed（診斷），there had not seemed to be anything worth doing. But shortly after I came out of hospital. I suddenly realized that there were a lot of worthwhile things I could do.” Hawking married, found a job at Cambridge University, where he still works today, and had three children. He also went to do some of the most important scientific research ever carried out.

His story shows that nobody, however bad their situation is, should lose hope. “Life is not fair,” he once said, “ You just have to do the best you can in your own situation.”

科目：高中英語 來源：江蘇省鎮(zhèn)江市2016-2017學年高一下學期期末考試英語試卷 題型：閱讀理解

An American company has built a new drone（無人機）that could improve the speed of deliveries（送交的貨）.

The drone is very different from other unmanned aircraft.It is made almost completely out of cardboard and has no motor.It can be packed with materials and sealed up with tape.

Because the drones do not have a motor,they are designed to be dropped from airplanes.Hundreds of drones could be sent out at once.Then they could be automatically guided to where they are supposed to go.The company says these drones could then complete deliveries to different places over an area covering hundreds of kilometers. The drones look bigger than the paper airplanes we used to make as kids.But this light flyer is not a toy.It is aerodynamically designed and equipped with a small computer,a battery and sensors to guide it to the ground.

The drones are being developed by Otherlab—a technology research company in San Francisco,California.It calls the drone a "Sky Machine."

The company says it can travel about 150 kilometers at speeds up to 88 kilometers an hour.Now,it can carry materials weighing up to one kilogram,but future models are expected to carry larger loads.

One of the drone's main advantages is that it does not have a heavy motor or large battery.This allows more room for materials and makes the drone cost less to build and operate.

The Otherlab development team has called its invention the "Ikea of drones."This is because it is packaged similarly to products from the Swedish furniture maker Ikea.The drone arrives as flat pieces of pre-cut cardboard that can be quickly and easily put together.

The technology that guides the drone can make it land within 10 meters of its target,according to Otherlab. Unlike other drones,even a crash landing is acceptable.The company says the drones can also be reused.

Once the drone completes its delivery,it can be thrown away and the cardboard material will likely break down within a few months.

The company has received money from the U.S. Department of Defense to carry out research on the drones.The money came from the Defense Advanced Research Projects Agency.The agency is attempting to find the best delivery vehicles that can disappear after their missions are complete.The U.S. military has a need for delivery drones.But it wants to simplify and lower the cost of using them.Otherlab's Sky Machines are an attempt to fill that need.

Military drones can also be stolen and studied by others if found after use.Before they can truly disappear,the electronic materials inside must also somehow disappear.Researchers are still working on ways to get the technology itself to self-destruct.

1.What does Paragraph 3 mainly talk about?

A. Why the new drone is invented.

B. What the new drone is equipped with.

C. How can the new drone get to the ground.

D. Why the new drone is designed like paper airplanes.

2.Why is the invention called the "Ikea of drone"?

A. Because it's a product made by Ikea.

B. Because it uses the idea from Ikea.

C. Because it's built at a low cost like furniture of Ikea.

D. Because it's made up of pre-cut cardboard.

3.Which of the following statements is the advantage of the new drone?

A. It can land near its target.

B. It has a light motor inside.

C. A crash landing is not acceptable.

D. Its load weighs far more than one kilo.

4.What about Otherlab's Sky Machines can be inferred from the last two paragraphs?

A. They have been built by the US military.

B. Research is being carried out on their improvement.

C. They are now often stolen and studied by others after deliveries.

D. The electronic materials inside will destroy themselves after use.
